SPECIFICATION forming part of Letters Patent No. 640,236, dated January2, 1900;

Application filed August 1'7, 1898. Seria1No.688,83l. (No model.)

To ctZZ whom it may concern:

Be it known that I, JAMES S. SPUReEoN, a citizen of the United States,residing in the county of Henry and State of Kentucky, have in vented anew and useful flame-Fastener, of which the following is aspecification.

This invention relates to hame-fasteners of that class embodying atoggle-lever; and the object of the present invention is to provide animproved device having the parts adj ust ably connected together,wherebythe fastener may be fitted to hames of different sizes.

To this end the present invention consists in the combination andarrangement of parts, as will be hereinafter more fully described, shownin the accompanying drawings, and particularly pointed out in theappended claim.

In the drawings, Figure 1 is an elevation of the device in openposition. Fig. 2 is a top edge view thereof in closed position. Fig. 3is an elevation of Fig. 2. Fig. 4: is a transverse sectional view on theline as 0;, Fig. 2.

The same numerals of reference are used to indicate like andcorresponding parts in each of the several figures of the drawings.

Referring to the accompanying drawings, the presentdevice embodiesopposite links 1 and 2 and an intermediate connecting togglelever 33,all formed of fiat metal plates of suitable size. The lever 3 is pivotedintermediate of its ends, nearer one longitudinal edge than the other,to the link member 2 upon a re movable pivot-pin 4, having atransverselydisposed head or thumb-piece 5. A plurality of openings 6are formed through the link 2 near its upper edge, whereby the lever maybe adjusted longitudinally upon the link. At one end the link is bentinto a hook 7, projected at the outer side of the link opposite thelever 3. A suitable leaf-spring 8 is fastened to the link, having itsfree end engaged against the inner side of the end of the hook toprovide a convenient snap-hook for connecting the link with one end of ahame. The free end of the lever is provided with a lug 0, extendingtransversely outward from the lever and away from the link 2 andproviding a latch for the lever, as will be hereinafter fully described.The other link 1 is pivoted,

as at 10, to one end of the lever, opposite the lug end thereof and uponthat side opposite the link 2. This pivotal point 10 is located near oneend and near the lower longitudinal edge of the link and to one side ofthe longitudinal axis of the lever, opposite the pivotpin 4. The outerfree end of thelink is formed into a hook 11, projected at the innerside of the link and located upon the same side of the device as is thehook 7,- and may be provided with a spring, as described, for the otherhook, as desired. Near the outer end of the link and in the u nderlongitudinal edge thereof is provided a notch 12, adapted to receive thelug 9 of the toggle-lever and lock the device when in fastened position.

In the operation of the device the lever 3 is thrown into a positiontransversely of the link members, which separates the links and movesthem longitudinally apart. The hooks 7 and 11 are then engaged with therespective movable ends of the hames, and by throwing the free end ofthe lever around toward the link 1 both links are drawn together byreason of their toggle connection, and the hames are tightened, as willbe understood. lVhen the device is being tightened, the toggle-lever isthrown around until its lug 9 engages with the notch 12 of the loweredge of the link 1, whereby the parts of the device are effectivelylocked against accidental loosening.

By reference to Fig. 2 it will be noted that the pivot-points at and 10,respectively, are located upon opposite sides of the longitudinal axisof the fastener, whereby the tension tends to throw the free or lug endof the toggle-lever upward; but as the lug 9 is situated within thenotch 12 it will be apparent that the lever cannot be moved in thisdirection, and therefore the tension upon the device acts to lock thelever in a simple and eifective manner.

To fit the fastener to hames of different sizes, it is simply necessaryto engage the removable pivot-pin 4 with any desired one of the openings6 in the link 2, whereby the longitudinalthrow of the link members isadjusted, as will be understood.

In order that the toggle-lever may be readily disengaged from the notch12, the outer end of the lug 9 is enlarged, as at 13, and adapted toproject beyond the opposite face of the link member 1, and therebyprovides a convenient thumb-piece for disengaging the lever.

By reason of the combination of parts of the present invention a simpleand improved hame-fastener is provided which may be conveniently andeffectively adjusted to fit hames of different sizes and may beefiectively locked in its fastened position and also arranged forconvenient disengagement of the operatinglever from its locked position.

What I claim is- A hame-fastenercomprising the link 1 provided at itsouter end with a hook and having the notch 12 located at its lower edgeand arranged adjacent to the hook, the link 2 provided at its outer endwith a hook, and a locking-lever fulcrumed on the inner end of the link1 and adjnstably connected at its intermediate portion on the innerportion of the link 2, and provided at its free end with a lug orprojection 9 extending outward at an angle to form a handle orthumb-piece, and arranged to engage the notch 12, said lockingleveroperating in a plane between the links, whereby the lug or projection isadapted, when in engagement with the notch 12, to extend across the link1 so that the handle or thumb-piece will lie beyond the device and be ina position to be readily grasped by the operator, substantially as andfor the purpose described.
